Salivin Sugar Free Pastilles 25sSalivin Sugar Free Pastilles play a critical role in the maintenance of oral and dental health. Saliva is a complex fluid made up of secretions from the salivary glands, which help in cleansing the mouth, breaking down food, lubricating surfaces within the mouth, protecting teeth and gums, as well as helping us to taste, swallow and digest our food. Saliva is also vital in allowing us to talk. Any change in saliva flow can upset the delicate balance that normally exists in the mouth and leave the mouth feeling dry.
